Abstract
A taping head for applying a film of pressure sensitive adhesive to a receptor surface has a drive means for driving the adhesive to the applicating roller by driving a liner supporting the adhesive, and a dancing roll positioned between the apparatus for stripping the liner from the adhesive and the applicating roller adjusts the speed of movement of the film of adhesive to match the same with the application of the adhesive. The applicator is pressed against the receptor surface under the control of a compression device and a cutting device for adhesive severs the adhesive below the applicating roller and an air nozzle maintains the cut end of the adhesive in a position for subsequent application.
